How to Roast Cherry Tomatoes in the Oven

At A Glance

• Roast cherry tomatoes at 325°F for 45-60 minutes for sauces or 425°F for 20-25 minutes for blistered, snackable tomatoes with charred skins.
• Space tomatoes in a single layer – crowding the pan steams them instead of roasting them, and you lose all the caramelization.
• Add salt before roasting, add fresh herbs after; heat destroys delicate aromatics like basil.
• Roasted cherry tomatoes keep in the fridge for 5 days and freeze beautifully for up to 3 months.
• This guide covers both the slow-roast and high-heat methods, seasoning strategy, pan selection, and 7 ways to use the finished tomatoes.

I love making How to Roast Cherry Tomatoes in the Oven because it is one of the easiest ways to turn fresh tomatoes into something rich, sweet, and full of flavor. The first time I tried it, I could not believe how a few simple ingredients made such a big difference.

Over the years, I have roasted cherry tomatoes for pasta, salads, toast, pizza, and grain bowls. I have tested different oven temperatures and cooking times, so I know what works best for soft, juicy tomatoes with lightly caramelized edges. In this guide, I will show you every step, share my best tips, and help you get perfect results every time. Let’s get started and make a batch you will want to enjoy all week.

Why Roasting Changes Cherry Tomatoes Completely

Roasting turns cherry tomatoes from bright, slightly acidic little spheres into something far more concentrated, sweet, and complex. The science behind this is straightforward once you understand it.

A raw cherry tomato is about 94% water (Harold McGee, On Food and Cooking, 2004). When you roast them, two things happen at once. First, that water evaporates, concentrating the sugars and acids that give tomatoes their flavor. Second, the sugars on the surface hit the hot pan and caramelize – meaning they break down chemically and produce dozens of new flavor compounds that weren’t in the raw fruit.

At higher temperatures, you also get the Maillard reaction: the browning that happens when amino acids and sugars meet heat above 280°F. This is different from caramelization. The Maillard reaction is what gives the skins those dark, slightly bitter spots that balance the sweetness underneath. Per J. Kenji López-Alt (The Food Lab, 2015), this contrast between sweet, jammy interior and slightly charred skin is what makes blistered tomatoes so addictive.

The result after roasting: up to 60% less water by weight, tomatoes that are 3-4 times more intense in flavor, and a texture that ranges from jammy to almost sun-dried depending on your time and temperature.

The Roasting Temperature Guide: Slow vs. High Heat

The temperature you choose changes everything about the final result. Here are the four main approaches and when to use each.

Temperature	Time	Result	Best Use
300°F (150°C)	75-90 min	Very concentrated, almost dried, deep red	Pasta sauce base, freezing, tomato jam
325°F (163°C)	45-60 min	Jammy, collapsed, pools of juice in the pan	Bruschetta, grain bowls, soup base
375°F (190°C)	30-40 min	Soft with some browning, skins starting to split	Eggs, pizza topping, roasted veg sides
425°F (218°C)	20-25 min	Blistered, charred skins, still plump inside	Snacking, salad topping, quick pasta

I use 325°F more than any other temperature. The tomatoes collapse just enough to release their juice into the olive oil, and that liquid in the bottom of the pan is a sauce on its own. Pour it over pasta with nothing else and it’s one of the best things you’ll eat.

Step-by-Step: How to Roast Cherry Tomatoes

What You Need Before You Start

• 1 pint (about 300g) cherry tomatoes, washed and dried
• 2-3 tablespoons good olive oil
• 1/2 teaspoon flaky sea salt (Diamond Crystal or Maldon)
• A rimmed sheet pan or shallow roasting pan
• Optional: 3-4 unpeeled garlic cloves, fresh thyme sprigs

Step 1: Dry the Tomatoes Completely

Spread washed tomatoes on a clean kitchen towel and pat them dry. Surface moisture turns to steam in the oven, which slows browning and keeps the tomatoes from concentrating properly.

This step takes 30 seconds and most people skip it. Don’t skip it.

Step 2: Choose the Right Pan

Use a rimmed sheet pan (also called a half-sheet pan) or a shallow roasting pan. The rim stops the juices from running off the edge once the tomatoes burst. A 13×18-inch sheet pan is ideal for one pint of tomatoes; if you crowd them onto a smaller pan, they steam.

Avoid glass or ceramic baking dishes for high-heat roasting. They retain moisture poorly at 425°F and create uneven hot spots (America’s Test Kitchen, The Complete Cookbook for Two, 2013). Dark-colored metal pans absorb more heat and speed up caramelization – this is a good thing.

Step 3: Dress and Season the Tomatoes

Put the dry tomatoes in a bowl. Add 2-3 tablespoons of olive oil and toss until every tomato is coated. Season with 1/2 teaspoon of flaky salt and toss again.

Do not add sugar. Cherry tomatoes have enough sugar already. Adding more makes them too sweet and throws off the acid balance.

If you’re adding garlic, toss in 3-4 whole unpeeled cloves at this stage. They’ll roast slowly and you can squeeze the soft garlic out later.

Step 4: Spread in a Single Layer

Pour the tomatoes onto the pan and spread them out so they aren’t touching. For one pint of tomatoes on a standard sheet pan, you should have room to spare. If they’re touching, move them apart. If you have two pints, use two pans.

Space matters more than almost anything else in this process.

Step 5: Roast

Place the pan on the center rack of a preheated oven. Use the timing chart above based on your target temperature.

At 325°F, start checking at 40 minutes. At 425°F, check at 18 minutes. Every oven runs slightly differently.

Step 6: Know When They’re Done

You’re looking for four things:

1. Collapsed and wrinkled skins – The tomatoes should look deflated, not round and plump.
2. Split skins – At least half should have burst and released their juice into the oil.
3. Caramelized juice – The liquid pooling around the tomatoes should be syrupy and slightly thickened, not watery.
4. Color – At high heat, you want some dark spots on the skins. At low heat, the color should deepen from bright red to a darker, more concentrated red.

If the juices in the pan are still thin and clear, keep going. Thin juice means the water hasn’t cooked off yet.

Step 7: Rest Before Serving or Using

Let the pan sit for 5-10 minutes after you pull it from the oven. The juices thicken slightly as they cool. If you add fresh herbs like basil, add them now – the residual heat wilts them gently without destroying their flavor.

Seasoning Strategy: Before, During, and After

Salt timing is the thing most home cooks get wrong with roasted tomatoes.

Before roasting: Add salt and olive oil. The salt draws a little moisture from the surface, which actually speeds up browning. This is the stage for sturdy aromatics: garlic, thyme, rosemary, dried oregano.

During roasting: Leave the tomatoes alone. Stirring them more than once breaks them apart prematurely and prevents the undersides from caramelizing against the pan.

After roasting: This is when you add fresh basil, parsley, or any soft herb. Balsamic vinegar (1-2 teaspoons, drizzled over the finished tomatoes) is good here too. A squeeze of lemon juice can sharpen the flavor if the tomatoes taste flat.

Per Samin Nosrat (Salt Fat Acid Heat, 2017), acid added after cooking brightens flavors that high heat can dull. Roasted tomatoes respond well to this – a small splash of sherry vinegar or lemon right before serving makes a real difference.

Fresh vs. Canned Cherry Tomatoes: Which Roasts Better

Fresh cherry tomatoes give better results almost every time. They roast with their skins intact, which creates the texture contrast between chewy/charred skin and jammy interior. Fresh tomatoes also have higher natural sugar content than canned, which means more caramelization.

Canned cherry tomatoes (San Marzano or Mutti brand whole cherry tomatoes in juice) are acceptable when fresh are out of season or unripe. Drain them thoroughly before roasting, and expect a softer, less textured result. The skins are already softened by the canning process, so they won’t give you that blistered, charred-skin effect.

The one advantage of canned: the flavor is consistent year-round. A winter supermarket cherry tomato grown in a greenhouse and shipped 2,000 miles is often less flavorful than a good canned tomato (Bon Appétit, “The Case for Canned Tomatoes,” 2022). If fresh tomatoes feel mealy or pale, go with canned.

For both, drain off as much liquid as possible before the tomatoes hit the pan.

Convection vs. Conventional Oven: Which Gives Better Results

Convection wins for roasting cherry tomatoes, but only at lower temperatures.

Conventional oven: Heat comes from the top and bottom elements. The air inside is still. This means moisture from the tomatoes has nowhere to go and stays trapped around the pan, slowing the drying-out process. At 325°F, a conventional oven takes about 50-60 minutes for fully roasted results.

Convection oven: A fan circulates the hot air continuously. This moves moisture away from the pan surface faster, which speeds up browning and evaporation. At 325°F with convection, you’ll hit the same results in 35-45 minutes. Per America’s Test Kitchen (Cook It in Your Dutch Oven, 2019), convection reduces roasting time by about 25% for most vegetables.

At high heat (425°F), the difference is smaller. Use convection if you have it; reduce temperature by 25°F if your oven runs hot with convection on.

Common Mistakes That Ruin Roasted Cherry Tomatoes

Overcrowding the pan. This is the most common mistake. Tomatoes touching each other trap steam between them. Steam cooks the tomatoes but prevents browning. You end up with soft, waterlogged tomatoes instead of caramelized ones. One pint per standard sheet pan is the rule.

Using the wrong pan. Glass baking dishes and ceramic casseroles are poor conductors of heat. The tomatoes on the edges overcook before the ones in the middle are done. Use a metal sheet pan.

Under-seasoning. Tomatoes need more salt than you think. They’re mostly water, and a significant amount evaporates. The salt that seemed right before roasting can taste too light on the finished product. Season again after roasting if needed.

Skipping the resting step. Pulling tomatoes straight from the oven and immediately using them misses the 5-10 minute period where the juices thicken and the flavors settle. The difference is noticeable in the final dish.

Adding fresh herbs before roasting. Basil turns black and bitter at 325°F+. Parsley loses its freshness. Add delicate herbs only after the pan comes out.

What to Do with Roasted Cherry Tomatoes

Roasted cherry tomatoes are useful in more ways than most people use them.

Pasta: Crush the roasted tomatoes into their own juice and toss with pasta, a splash of pasta water, and Parmesan. This is a complete sauce with no additional cooking needed. Serious Eats calls this method one of the fastest weeknight pasta techniques available (Serious Eats Weeknight Pasta Guide, 2023).

Bruschetta: Spoon over toasted bread rubbed with raw garlic. Add fresh basil and a drizzle of olive oil. The slow-roasted version (325°F) works better here than the high-heat version because the tomatoes are juicier.

Eggs: Spoon roasted tomatoes into a shallow pan, crack eggs directly into the gaps, and cook covered on the stovetop until the whites set. The tomato juice becomes the sauce for the eggs.

Grain bowls: Stir through warm farro, quinoa, or rice with arugula and goat cheese. The tomato juices dress the grain.

Pizza topping: Place on pizza after baking, not before. High-heat roasted tomatoes (blistered, with charred skins) work well here. Adding them pre-bake makes the crust soggy.

Freezing: Spread roasted tomatoes on a sheet pan and freeze solid, then transfer to freezer bags. They keep for 3 months and go straight from frozen into soups, stews, and braises. This is worth doing in peak summer when cherry tomatoes are cheap.

Soup base: Blend slow-roasted tomatoes (300-325°F) with their pan juices, roasted garlic, and a little stock. Season with salt, smoked paprika, and black pepper. This is a better tomato soup than anything you can make with canned crushed tomatoes.

My Personal Roasting Routine

I’ve roasted more cherry tomatoes than I can count – in restaurant prep kitchens turning out 20 sheet pans at a time, and at home turning out one pan for a Tuesday night pasta.

My default: 325°F, 50 minutes, one pint of tomatoes on a half-sheet pan, 2.5 tablespoons of olive oil, half a teaspoon of Diamond Crystal kosher salt, 4 unpeeled garlic cloves.

The garlic cloves go in with the tomatoes. After 50 minutes, I squeeze the soft garlic out of the skins and stir it through the tomato juices in the pan. It dissolves into the liquid and gives the whole pan a sweet, roasted garlic flavor without any sharp bite.

When I want the high-heat version – for a salad topping or to eat with cheese and crackers – I go to 425°F for 22 minutes. I want the skins dark and blistered but the insides still plump. At 22 minutes in my oven (a standard home convection oven), that’s exactly what I get.

The one thing I never do: I never walk away and forget about them. Tomatoes go from perfectly roasted to burnt quickly, especially at higher temperatures. Set a timer at the early end of the range and check them yourself.

Frequently Asked Questions About Roasting Cherry Tomatoes
